Which company owns MAC address prefix 84:D6:C5?

MAC address prefix 84:D6:C5 is registered to SolarEdge Technologies in the IEEE Organizationally Unique Identifier (OUI) registry. Any device whose MAC address begins with 84:D6:C5 has a network interface built by SolarEdge Technologies.

What is the OUI 84:D6:C5?

84:D6:C5 is an Organizationally Unique Identifier — the first three octets (24 bits) of a MAC address, assigned by the IEEE to SolarEdge Technologies. It covers every address from 84:D6:C5:00:00:00 to 84:D6:C5:FF:FF:FF, or 16,777,216 addresses in total. It is also written 84-D6-C5.

How do I find the manufacturer of a MAC address?

Take the first three octets of the address — in 84:D6:C5:00:00:00 that is 84:D6:C5 — and look that prefix up in the IEEE OUI registry. If the second-lowest bit of the first octet is set, the address is locally administered (a randomized or private MAC), which belongs to no manufacturer and will not resolve; modern phones and laptops use these by default on each network.

Where is SolarEdge Technologies located?

SolarEdge Technologies is listed at 1 Abba Eban St. Herzelia IL 46725 in the IEEE OUI registry entry for 84:D6:C5. This is the address the organization registered with the IEEE, which may differ from its current operating address.

How many MAC prefixes does SolarEdge Technologies own?

SolarEdge Technologies holds 2 OUI prefixes in the IEEE registry, of which 84:D6:C5 is one. A device made by SolarEdge Technologies could carry a MAC address from any of them.
